I am trying to upgrade my Winfrom project from .net6 to .net7 Rc1 after changing the Target Framework and updated the NuGet packages and when I run the project I get this error
GenericArguments[0], 'System.Int32', on 'T MaxFloatT' violates the constraint of type 'T'.
on this line of code
System.Windows.Forms.Application.Run(host.Services.GetRequiredService<XtraMain>());
This is the code in Program.cs
[STAThread]
private static void Main()
{
WindowsFormsSettings.ForceDirectXPaint();
DevExpress.UserSkins.BonusSkins.Register();
DevExpress.Skins.SkinManager.EnableFormSkins();
System.Windows.Forms.Application.EnableVisualStyles();
System.Windows.Forms.Application.SetCompatibleTextRenderingDefault(false);
System.Windows.Forms.Application.SetHighDpiMode(HighDpiMode.SystemAware);
using IHost host = CreateHostBuilder().Build();
System.Windows.Forms.Application.Run(host.Services.GetRequiredService<XtraMain>());
}
private static IHostBuilder CreateHostBuilder() =>Host.CreateDefaultBuilder()
.ConfigureAppConfiguration((context, builder) =>
{
builder
.AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
.AddJsonFile($"appsettings.{context.HostingEnvironment.EnvironmentName}.json", optional: true)
.AddEnvironmentVariables();
})
.ConfigureServices((context, services) =>
{
services.AddScoped<XtraMain>();
services.AddPersistenceServices(context.Configuration);
services.AddApplicationServices();
services.AddSingleton<IFormFactory, FormFactory>();
});
And this is the StackTrace:
